Summary

   This instrument is made and designed as per ASTM D***8 and T********0 Bending Beam Test of JTG E******1 Standard Test Methods for Bitumen and Bituminous Mixtures for Highway Engineering. It is suitable to determine the strain rate of bending creep of bituminous mixtures under specified temperature and loading stress in horizontal condition to evaluate the deformation performance of bituminous mixtures.

I. Main technical features

1. It adopts advanced sensor technology and micro-computer processing technology. It has functions of parameters setting, measurement calibration, automatic test control, automatic data collection and real-time clock.

2. It can collect the creep value and test temperature at the same time and looking for the stability region of bending creep. The deformation value, test temperature, curves, result and time will be shown on the LCD directly.

3. It can store **0 groups of test data. Operator can check them at any time.

4. It equips a RS**2 communication port to achieve communicating with PC. Data process, store, print and display can be done by the computer. The whole procedures can be operated by the computer too.

5. It adopts temperature control combining electric heating with compressor refrigeration. The temperature control accuracy is high.
